Your best bet is Eblag... I looked all over the scrappies wanted £100 8O Got a Power one in the right colour off ebay for £27. Took me a while to fine it.
there are a few mav/terranos being broken on ebay, I bought a maff sensor from a maveric for my terrano for £20 gave it a clean and it works perfectly, keeping my own for a spare.....bri
